Haley is making cake for her party. she needs to make 6 servings of cake for every 3 people. if each cake pan contains 12 servin

Solnce55 [7]

6 servings = 3 people
1 cake=12 servings which feed 6 people
6/x=3/21
3x=126

Annie invests £9500 for 5 years in a savings account. She gets 1.8% per annum compound interest. How much money does Annie have

Trava [24]

Answer:

£10386.34

Step-by-step explanation:

The amount in an account for a principal P saved at compound interest for a period of n years at an annual rate of r% is calculated using the formula:

$A(n)=P(1+r)^n$

In this case:

Principal, P=£9500

r=1.8%=0.018

n=5 years

Therefore:

$A(5)=9500(1+0.018)^5\\=9500(1.018)^5\\=\£10386.34$

At the end of 5 years, Annie will have £10386.34

Find the value of x and y in the diagram below.

defon

Answer:

Step-by-step explanation:

cos 30 = 9/x

x = 9/( $\sqrt{3}/2$ ) = 6 $\sqrt{3}$

(6 $\sqrt{3}$ )² - 9² = x²

x² = 27

x = 3 $\sqrt{3}$

What is the gradient of the graph shown? Give your answer in simplest form

gogolik [260]

Answer:

gradient = 2

line: y = 2x - 4

Step-by-step explanation:

Find the slope from the slope intercept formula

y = mx + b

b is the y intercept

b = -4 and the point is (0,-4)

So far the equation looks like this.

y = mx - 4

Use the other intercept (x intercept) to find m

x = 2

y = 0

0 = m*2 - 4 Add 4 to both sides

4 = 2m Divide by 2

4/2 = m

m = 2

So the gradient or slope is 2
